In the books, the entire plot of Goblet of Fire is foreshadowed when Harry and Ron are doing their divination homework. While they're doing their divination homework, Harry and Ron mention: a "danger of burns" (1st task), losing a "treasured possession" (2nd Task), being "stabbed in the back by someone you thought was a friend" (either Barty Crouch Jr. or Ron being an ass after Harry was chosen as champion) and coming "off worse in a fight" (the fact Voldemort comes back and can now touch Harry).
